I have been reading your posts regularly. I also, I had put some comments and you have replied for it. But, to read the reply, I have to rivist the post and then only I will know about it. Is there any way, to let us know by mails that there is reply waiting for me. And also a trigger for new posts?

Just like yahoogroups. Or you can open a group in yahoo or google and we can join that. Once there is new post, you just post it in that group and we will get a mail.
